Robert, actually, yes and no, as follows....
The "Casino Legends Hall of Fame" and Museum, as operated by Steve Cutler, did leave the Tropicana some time ago, but did not "move" to another public location. In it's place, the operator of the giftshop at that location (Rich Burgel) took over that vacated space and set-up his own gaming-related museum. I believe that it was an extension of the gaming museum he operated at a Downtown (Las Vegas) location.
At this point in time, the Casino Legends Hall of Fame and Museum is without a public venue ( ) and Burgel operates an antique mall-like store on Main Street (Las Vegas) that also includes some portions of his museum operation.
